French energy provider, EDF, has reduced electricity production at nuclear sites in response to high temperatures in three regions facing heatwave warnings. While three reactors have been affected, EDF assures the public that there is no safety risk. Heat-related incidents are not uncommon for EDF, as shown by their climate change action plan released last month.
The closure of a reactor at the Bugey nuclear power plant near Lyon, along with production cuts at the Saint-Alban and Tricastin sites, highlights the challenges of maintaining nuclear processes during extreme heat. Nuclear reactors rely on water to cool the reactors and produce electricity, but in times of high temperatures, this process can be compromised.
EDF is following safety regulations established by the French Nuclear Safety Authority (ASN) to ensure that thermal discharges do not harm the environment. These regulations prevent sites from releasing water that is too hot back into rivers and lakes.
Despite these challenges, EDF estimates that annual production losses linked to water resources will only amount to 1.5% in 2050, with current losses at 0.3% per year. The firm remains committed to managing risks associated with heatwaves and maintaining safety standards at their nuclear sites.
As three French departments remain under heatwave warnings, EDF has temporarily reduced production to comply with thermal discharge regulations. With storms now replacing the hot weather in some areas, the energy provider continues to monitor the situation and prioritize safety amidst the challenging conditions.
